DEVICE FOR JOINTING THE TEETH OF SAWS.

SPECIFICATION forming part of Letters Patent No. 355,307, dated January 4, 1887.

Application filed August 26,1986. Serial No. 211.941.

(No model.)

' have invented a new and useful Improvement in Saw-Jointers, of which the following is a specification.

My invention relates to improvements in saw-jointers; andit consists of the peculiar combination and novel construction and arrangement of parts, substantially as hereinafter fully described, and particularly pointed out in the claims.

The present invention is more particularly designed as an improvement upon the com bined saw jointer and gage patented to me on the 22d day of April, 1884, by Letters Patent N o. 297, 513; and my invention has for its object to provide a saw-j ointer of the class shown in my said patent with means for guiding the device on the saw as it is moved or reciprocated back and forth over the teeth of the saw, and, further, to provide the jointer with improved means for holding the file very firmly in place thereon, so that it is not liable to become detached when the device is in use.

In the accompanying drawings, Figure 1 is a perspective view of a saw-j ointer embodying my improvements. Fig. 2 is a sideelevation of my improved jointer adjusted upon a saw for jointing the saw-teeth thereof. Fig. 3 is asimilar view, corresponding to Fig. 2, looking at the opposite side of the saw. Fig. 4 is a side elevation of the device adjusted upon a saw for jointing the raker-teeth thereof.

Referring to the drawings, in which like letters of reference denote corresponding parts in all the figures, A designates my improved jointer for saw and raker teeth, which comprises a head, 13, having a central depressed portion, a, provided with a longitudinal vertical slot, b, which is located midway of the sides of the depressed portion. Qn opposite sides of this slotted depressed portion the head has integral arms 0, which are elevated or raised above the depressed portion, and the extremeties of the arms have depending flanges c, which are beveled on their inner opposing faces to adapt them to more snugly fit the inclination of the saw-teeth. The central depressed portion of the head has a lateral arm,

(1, to which is swiveled a vertical standard, D, that rises from a horizontal base, E, said base having two arms, 6 e, which project laterally from opposite sides of the vertical standard, the arm 6 having a vertical threaded opening, f, formed therethrough, in which works a vertical binding or clamping screw, F, that has a looselyswiveled head,f, at its upper end. This part of my invention is substantially the same as the device shown in my prior patent, hereinbefore referred to, and no novelty is herein claimed on the said device.

My present improvement consists in providing the head of the jointer with guides G, which are arranged beneath the head and formed integral therewith. These guides are arranged in a horizontal posit-ion and in line with each other, and the outer ends of the guides are connected to the depending flanges a, while the inner ends of the said guides are connected to a depending flange, G, that is formed integral with the head at the middle thereof. A space, I, is left between the contiguous inner ends of the guides G, to permit the headf of the clamping-bolt to ,pass between the end of said guide and bear against the file, so as to clamp the latter to thejointer. The vertical lugs or flanges c at the ends of the head are provided with recesses or notches H, which are formed therein above the guides, as shown, so that a file, as J, can be fitted in the notches and the clamping-screw turned to press the file against the upper edges of the notches or slots, as shown. The outer sides or faces of the guides are made straight and smooth, so that when the jointer is in use they will slide Very freely against one of the faces of the saw.

This being the construction of my improved saw-j ointer, the operationthereof is as follows: When it is desired to file araker-tooth, the de: vice is adjusted on the saw so that the upper ends of the particular tooth which it is .desired to file shall pass through the vertical slot in the central depression of the head, while the sawteeth on opposite sides of the rakertooth being operated upon fit in the spaces be tween the central depression and the flanges c of the said head. The raker-tooth is ,filed while the deviceis in this position, after which thejointer is fitted on another tooth and the operation again repeated. v

To joint the saw-teeth, a file is placed in the A notches or recesses H in the depending flanges,

and the clamping-screw is turned to press the file against the upper sides of the said notches, to thereby securely connect the file to the jointer.

The device is adjusted upon the saw so that the file rests on the teeth thereof, and the smooth faces of the guides bear orin'ipinge against one side of the saw. The device and the file connected thereto are moved or reciprocated lightly over the saw-teeth to joint them, and

the guides serve to keep the device in its proper position on the saw.

I direct especial attention to the end flanges, having the notches or recesses and the guides arranged beneath the head and out of contact with each other at their inner ends, to leave an intermediate space through which the head of a clamping-boltis adapted to pass to clamp or hold a file in the slots or recesses of the head, as therein lies the gist of my present invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a saw-jointer, a head having the denected at their inner ends with a central depending flange on the head, the inner ends of 5 the said guides being separated to provide an intermediate space, a standard connected to the head, and a clamping-screw working in the standard and having a head which passes through the space between the ends of the guides, substantially as described, for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
